The unofficial end of summer marks the official beginning of legal action against The Honest Company and its founders, including actress Jessica Alba.

The Class Action complaint filed Sept. 3 in the United States District Court of California alleges the company’s sunscreen is ineffective, and calls into question the company’s marketing claims for an array of its products.

The legal action follows an NBC5 Investigates report first aired on NBC5 Chicago last July, in which hundreds of customers like Gretta Stabler of Naperville voiced concerns about the product, after she says she followed directions in applying it but her 6-year old daughter still suffered a sunburn.
